The women's Karhu Fusion 2021 is a high cushion running shoe for neutral footed runners. With a plush yet propulsive ride, it's ideal for performance-oriented athletes seeking a shoe for up-tempo workouts or race day.

The new women's Fusion is lighter than previous versions and maintains a touch of rearfoot support while providing an even quicker transition. The women’s Fusion 2021 is the first shoe built by women for women. By adjusting the circumference volume at the instep and forefoot, Karhu offers a personalized women’s construction we call HeraFit. The renewed upper reduced weight while keep delivering a secure fit. The Fusion now features a shortened Fulcrum, the shortest in the collection, and a propulsion unit for an even faster feel. Lastly, extra cushioning is added to the forefoot for more protection at toe-off.

At Karhu, we know every runner has unique feet and precisely that given resulted in the new Fusion Ortix. The Fusion Ortix is built from a growing database of over 1.3 million 3D scans taken from runners’ feet. The Karhu Fusion is literally created by the runner, for the runner.
